SPECIFICATION forming part of Letters Patent No. 643,3 2, dated February 13, 1900..

Application filed November 29, 1898. Serial No. 697,762. (No model.)

To ctZZ whom it may concern:

Be it known that I, ROBERT S. \VEST, a citizen of the United States, and a resident of Cleveland, in the county of Cuyahoga, State of Ohio, have invented a new and useful Improvement in Fumigating-Lamps, of which the following is a specification.

This invention relates to certain new and useful improvements in fumigating-lamps.

My invention consists in the'pe culiar construction of a fumigating-lamp whereby an aromatic fluid may be burned without flame and which will impregnate the air of a room with the fumigant.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a view in side elevation of my improved lamp. Fig. 2 is a vertical central section through the same. Fig. 3 is a side view of the wick-tube. Fig. 4: is a plan view of the braided platinized asbestos disk or mantle, and Fig. 5 is a side view of the mantlecarrying spindle.

A represents the body of a lamp of any desired shape and size, which body is provided with the usual neck a. The fuminating fluid within the body is denoted by B.

0 represents a removable wick-tube, which is designed to carry the wick D and to slip loosely into the neck a of the lamp-body, it being provided with a rib c, by means of which it is suspended within such neck.

E represents a removable glass spindle provided with an enlargement 6 about midway between its ends, and F represents a circular mantle or disk of braided platinized'asbestos, which slips over the upper end of the spindle E and rests upon the enlargement e. The lower portion of the spindle E is designed to be inserted in the center of the wick D in such manner that the mantle will be in close proximity to the projecting end-of the wick, but not in contact therewith.

G designates a muffle which is fitted to rest upon the top of the bodyA of the lamp around the neck a and serves as a cover for the mantle or disk and the top of the wick.

This lamp is designed to burn any suitable aromatic fluid.

Vhen the lamp has been filled, the wick and tube are placed in position, with the spindle and mantle aboutas shown in the drawings. When it is desired to use the lamp, the wick is lighted and the flame allowed to burn until the platinized mantle has become thoroughly heated or incandescent, after which the muffle Gis placed over the top and quickly removed, thus extinguishing the flame; but the oxygen of the atmosphere mingling with the vapor thrown off by the fluid through the wick coming in contact with the heated mantle tends to keep such mantle in a steady glow and in a short time the room will be impregnated with the odor of the fumigant.

In the present device the mantle is always in the path of the ascending vapor from the wick, but spaced accurately therefrom by the enlargement on the spindle, and when once heated will continue to glow so long as there is any fluid in the lamp.

By forming the mantle of braided platinized asbestos I am enabled to produce a mantle which will be very strong and durable and considerably less expensive than the platinum wire coils and caps heretofore used, which coils and caps were very costly and easily broken or bent, so that they would come into contact with the wick, and thus as a result would not become incandescent and would be useless.

A lamp of this description will be found very useful in the sick-room, smoking-room, and various other places where it is desired to purify the air.

What I claim is The combination with the wick of a fluid fumigating-lamp, of a mantle consisting of a disk of braided platinized asbestos, and means for supporting the said mantle at the desired distance above the top of the wick, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 11th day of November, 1898.

ROBERT S. WEST.
